The smoker's article comprises a filter, a tobacco rod and a wrapper. The tobacco rod contains a catalyst consisting of a hydrated zeolite or a zeolite-like molecular sieve, the said zeolite or zeolite-like material being defined by the following formula:

Smoker's article

Humulones (I) are made by subjecting desoxyhumulones (II) to oxidation to form novel hydroperoxides (III) and reducing the latter. The humulones are used to make known isohumulones (IV) which are bitter substances useful in the beverage industry.

Process for making humulones and novel intermediates therefor

Certain allylmercaptans, some of which are novel, can be used to make novel flavorant and fragrance compositions. A novel method for making the allylmercaptans is disclosed.

Hydroperoxy-desoxyhumulones

Process for making flavorants by heating a liquid product obtained from milk products by enzymatic proteolysis and/or lactic acid fermentation.

Process for making and flavorants from milk products and compositions

The preparation and use of the novel 3,7-dimethyl-octa-2,6-dienyl-mercaptan as a new odorant and flavorant is disclosed.

3,7-Dimethyl-octa-2,6 dienyl-mercaptan perfume composition

Unsaturated compounds of the general formula: ##SPC1## Wherein R is defined hereinafter are prepared.

Process for making 1,3-diene hydrocarbons

There are disclosed novel .beta.-mercapto carboxylic acid esters and methods of producing the same. These novel esters are useful as odorants and flavorants.

Mercapto carboxylic acid esters

The known sweetening agent, neohesperidin dihydrochalcone is manufactured by reacting phloroacetophenone-4'-.beta.-neohesperidoside with isovanillin in the presence of a secondary amine and an organic acid in solution to give neohesperidin or its chalcone and then hydrogenating the reaction product in a manner known per se.
